Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a gemstone composite and a method for producing the same.

[Conventional technology]

Up until now, it has been common practice for multiple gemstones such as cut glass stones to be connected by suspending two adjacent gemstones by drilling a hole in the gemstone and inserting a metal wire through the hole. Such an approach is expensive and the holes detract from the aesthetic sense.

[Problem to be solved by the invention]

The object of the present invention is to provide a gemstone composite in which gemstones are bonded by a simple and labor-intensive method, and which does not impair optical aesthetics.

[Means to solve the problem]

The invention is based on the discovery that a solution can be achieved by bonding the above-mentioned jewelry with a string or cord made of shrinkable synthetic fibres.

The purpose of the present invention is to arrange a large number of jewels in parallel,
and forming side grooves on the gemstone, and holding the gemstone in a lattice forming body consisting of longitudinal filaments and transverse filaments on the other hand, at least either the longitudinal filaments or the transverse filaments. It is an object of the present invention to provide a jewel composite body, characterized in that it is formed of a synthetic material that is engaged in the side grooves formed on the jewel and has the longitudinal filaments and transverse filaments contracted.

A further object of the present invention is a method for manufacturing the above-mentioned gemstone composite, which method comprises forming side grooves in a lattice-forming body made of a shrinkable synthetic material and consisting of longitudinal and transverse filaments. Inserting the provided jewel, engaging at least one of the longitudinal filaments or the transverse filaments into a side groove on the jewel, and then shrinking the filaments. This is the manufacturing method.

The synthetic fibers to be used are preferably shrinkable thermoplastic synthetics. It is preferable that the longitudinal filaments and the transverse filaments constituting the lattice forming body are welded to each other at their intersections.

The gemstone complex can also be configured as a single row. It is adaptable to a wide variety of decorative purposes. Such an arrangement is also applicable to decorative jewelry, such as bangles.

However, the gemstone composites can also be arranged in rows or in a sheet-like configuration. Such an arrangement can be used as a decorative surface and is particularly applicable to the lighting industry.

As used herein, the term "precious stone" is most commonly used in its broadest sense and includes all types of gemstones, particularly those relating to cut glass stones. The shape of this gemstone can vary widely, for example square, rectangular, octagonal, circular or oval. The size of the gemstone is also within wide limits, e.g. 5-100mm
It can be changed within the range of . The above-mentioned gemstones can be decorated with a wide variety of specifications. These gemstones can also be cut with highly variable cut faces. The jewel has side grooves for inserting synthetic fibers. The width and depth of the side grooves range, for example, from 0.5 to 5 mm. This side groove is defined according to the diameter of the synthetic fiber. The thickness of the synthetic fibers depends on the size of the jewelry and the required tensile strength.

The side grooves of the gemstone are formed only on the two parallel side surfaces to accommodate the longitudinal and transverse filaments. Alternatively, the side grooves can be formed as side transverse grooves and side longitudinal grooves for fitting both the longitudinal and transverse filaments on all four circumferences of the surface of the gemstone.

The invention will be explained in more detail with reference to the drawings depicting exemplary embodiments.

〔Example〕

Figure 1 shows a rectangular jewel 2 with longitudinal filaments 4.
1 and 2. The figure is retained by a lattice-forming body 3 formed by and transverse filaments 5. The longitudinal filaments 4 are arranged in longitudinally extending side grooves 6, while the transverse filaments 5 extend on the sides of the jewel 2. Alternatively, the transverse filaments 5 can also be arranged in laterally extending side grooves 7 (not shown). As a further alternative, it is also possible to arrange only the transverse filaments 5 in the laterally extending side grooves 7 and to direct the longitudinal filaments 4 to the sides of the jewel 2. The longitudinal filaments 4 are preferably welded at their intersections 9 with the transverse filaments. However, it is also possible to integrally form the lattice-forming body 3 by pressing or punching the transverse fibers and the longitudinal fibers together, or by using a suitable method such as flash gluing.

The synthetic fibers employed are manufactured from a shrinkable synthetic material. The lattice formation is sized to facilitate insertion of jewelry therein. The synthetic filaments snap into the side grooves of the gemstone, and as long as either the longitudinal filaments or the transverse filaments are anchored within the side grooves, the shedding effect of the gemstone is prevented. Ru. However, for aesthetic reasons it is advantageous to form both transverse and longitudinal filaments extending into each side groove.

After the gemstone is inserted into the lattice formation, the synthetic fiber is subjected to a shrinking process. This shrinkage process is usually accomplished by heat treatment. The thermoplastic synthetic fiber produced by the suitably employed cold working shrinks to its original state in the above heat treatment process. Shrinkage percentages of 3% to 5% or even more in severe cases are easily obtained. The shrinking action of the synthetic fibers can firmly hold the gem within the lattice formation. Suitable synthetic materials that produce a contractile effect include polyethylene terephthalate, polyethylene,
vinyl chloride, polypropylene, polystyrene,
These are polyacrylonitrile, polyamide and polycarbonate. Pyramid is particularly preferred.
In some instances, synthetic materials with reinforcing fibers may also be employed.

Synthetic materials that have been subjected to orientation treatment or stretching treatment are preferred because of their high strength.

The appropriate shrinkage temperature is selected depending on the synthetic material employed. For example, the shrinkage process can be accomplished at temperatures within the range of 100°C and 120°C by immersion in a suitable high temperature liquid.

Of course, the types and arrangements of the above-mentioned gemstones are diverse. The spacing between gems, the size of the gems and their design can be varied at will. Depending on the purpose of use and the stress caused by it,
Thin or thick synthetic fibers of various strengths are employed. The diameter of the synthetic fibers is, for example, in the range from 0.3 mm to 5 mm.

The creative jewel composite of the invention can be produced according to very simple and economical specifications and has particularly enhanced aesthetics, for example if thin transparent or colored synthetic fibers are used. It may be characterized by its value. The gemstone composite can be used in a variety of applications. The free ends of the filaments can be made into a simple and reliable connection in different ways.

FIG. 2 shows an embodiment of a sheet-like product with a sheet-like arrangement of jewels 2. FIG. The individual jewels 2 are integrally joined to the grid-forming body 3 by longitudinal filaments 4 and transverse filaments 5, which define it. Each filament 4 and 5 extends into a side groove (not shown in the top view) of the jewel 2. Such a sheet-like arrangement is particularly suitable for decorative purposes and is particularly applicable to lighting installations.
